Poor plasticization from improper screw rotation speed of PCTG injection machine
Problem Phenomenon
Improper rotation speed selection causes poor plasticizing quality.
Cause Analysis
Too low rotation speed causes insufficient plasticizing, material not melting; too high generates heat degradation.
Solution
Set a reasonable screw rotation speed according to PCTG melt characteristics.
Key Takeaway
PCTG screw rotation speed is a plasticizing quality variable.
